At a Glance: Conical tube-to-thread straight fitting: 5/16" tube to 3/8" male connection

When a 5/16" tube run needs to connect into a bigger 3/8" threaded port, you want a fitting that does the job cleanly—without a bulky stack of adaptors. The AirCraft SB6805C brass conical straight fitting is a compact tube-to-thread connector that links 5/16" pneumatic tubing to a 3/8" male thread in a straight-through layout. It’s ideal for neat pneumatic installations on manifolds, air prep units, control circuits and general compressed-air plumbing where reliable sealing and serviceability matter.
